The PKCS#7 parser in OpenVPN 3 Core Library versions through 3.8.3 did not properly validate the parsed data, which would result in the application crashing.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
